'14 Claims. ((31. 271-61) Our invention relates to sheet magazines forprinting presses of the same general character as the stock magazinedisclosed in Patent No. 1,694,015 of December 4, 1928 which eventuatedIn our previously patenteddevice, as in the present case, themagazineis'pivotally mounted atone end thereof at one side of a printingpress and is swingable horizontally from closed, operative positiontransversely of the press at the front thereof to an open, inoperativeposition along the side of the press where it is out of the way ofthe-pressman' during make ready.

' Our present invention has for an object thereof to provide-{improvedmeans for supporting the free end of the swingable magazine in itsclosed, operative position and for releasably securing the magazine insuch position. n 7

Another object of the invention is to provide improved means fortransmitting motion to the sheet advancing mechanism of the magazine.

More specifically it is an object of our invention to supply for thefree end of the swingable magazine a self-latching support havinglatching means for accurately disposing the magazine in its closed,operative position and which supplies a medium providing for thecontinued support for the free end of the magazine when it is swung openfrom its said operative position.

Another object of the invention is to provide for the free end of aswingable magazine selflatching supporting means capable of adjustmentto accommodate the magazine in different operative positions thereof andhaving cooperating latching elements which remain'relatively undisturbedin various adjustments of said supporting means. n n

A further object of the invention is to provide a magazine latchingdevice of the present character including a spring which operatesto holdthe magazine relative to the supporting press frame and with suchfirmness as to prevent vibration and the rattling of parts.

An additional object of theinvention is to provide in the driving trainfor operating the sheet advancing mechanism of the magazine a swivelingconnection wherein the post, on which the magazine swings, is embodiedas an element.

With the foregoing and other objects in view, which will appear in thefollowing description, the invention resides in the novel combinationand arrangement of parts and in the details of construction hereinafterdescribed and claimed.

In the drawing, Fig. 1 is a perspective view of a sW-ingable sheetmagazine embodying our in-' vention, the same being shown in connectionwith a platen press of the familiar Gordon type-Fig. 2 and Fig. 3 arevertical sectional views showing in detail the construction of thesupport at'the free end of the magazine and illustrating par- 5ticularly the latching mechanism for said support, and Fig. 4 is avertical sectional view in detail illustrating the swiveling connectionin the driving train which operates'the sheet advancing mechanism of themagazine.

Referring to the drawing, the illustrated press parts, which will berecognized at once include the usual side frame brackets 10 and gearguard 11. The platen, designated by the numeral 12, is shown in its openposition. The crank disk 13 and the front shaft 14 on which said disk ismounted are shown together with a portion of the side arm 15 and aportion of the rollerframe link 16 at one side of the press.

The sheet magazine portrayed includes an inclined bed plate 17 forsupporting a pack of sheets on edge, said'plate having end frames 18thereon in which is slidably guidedan inclined back rest 19 for suchsheets. i r

A supporting post 20 for the magazine is swivelingly socketed in a bore21 in a boss 22 on the gear guard 11 and is held at different elevationsby means of a rest in the form of a collar 23 which bears on said boss,said collar being adjusts ably secured to said post by means of a setscrew 24 threaded in the collar. A horizontal supporting arm 25carried'by the post 20 is horizontally andangularly adjustable thereon,a reduced end 25 -of said arm, circular in cross section, being insertedina transversebore 26 in said post 20, the adjustment of the arm .25with respect'to the post 20 being maintained by means of a set screw 27threaded in the post and adapted to be turned against said reduced end25 of said arm. The

bed platel'l of the magazine proper is trunnioned 40 on the supportingarm 25, a boss 28 being formed at one end of said bed plate and insertedin a transverse bore 29 in said arm, the boss 28 normally being heldagainst turning in said arm by means of a set screw (not shown) threadedin the arm and turned against said boss. Swingably mounted, as aboveindicated, on the swiveling post 20, the magazine proper may be swungforth and back into and out of operative relation across the front ofthe press (Fig. 1) and may be adjusted to'secure the desired accuratedisposition thereof, in its operative relation, through an adjustment ofthe post 20 in the gear guard 22 foot 31 having a toe 32 and heel 33.Inserted through vertical slots 34 cut in opposite walls of the hollowfoot 31 is a latch lever 35, said lever being pivoted to said foot bymeans of a horizontally disposed pintle 36. A socket 3'? consisting ofan axial bore in the lower portion of the leg receives and holds anexpansion spring 38 which bears at its lower end against the upper edgeof the latch lever at the rear of the pintle 36. Said lever 35, unlessotherwise positioned against the action of said spring 38, is caused bysaid spring tobear against the limit stopv 39 (Fig. 2),

at the bottom of the rear slot 34 in the shoe 31. The forward end of thelatch lever 35 projects through the front slot 34 in the shoe and at itstip has a beveled cam surface 40 extending rearwardly from the loweredge of the leverto the upper edge thereof. Cut in the latch lever 35immediately at the rear of the cam surface 40 is a V-shaped notch 41which cooperates with a latch pin 42. This pin 42, occupying ahorizontal position, is mounted at one end thereof in an upright car 43formed integrally with an elongated latch block a, said block being ahollow structure consisting of a side wall 44 having an integral topflange 45, bottom flange 46 and end flanges 47. Slots 48 (Fig. 3),formed in the bottom flange 46 of the block a and extending lengthwiseof said block, receive threaded anchoring studs 49 which are threaded inthe frame bracket 10 at the side of thepress'opposite the gear guard 11.Bearing nuts 50 on said studs 49 engage the underside of the lowerflange 46 and lock nuts 51 on said studs engage the upper side of saidlower flange.

When the magazine is latched closed in its operative position (Fig. l),the latch lever 35 is disposed as shown in Fig. 3 with the tapered sidesof the notch 41 in said lever engaging the latch pin 42. To swing themagazine away from its operative position, the pressman" grasps theangularly disposed handle 52 at the rear end of the lever 35 and liftsupwardly thereon swinging I said lever out of engagement with the latchpin 42 and into the position shown in dotted lines in Fig. 2, whereinthe lower edge of the forward end of said lever bears against the limitstop 53 at the bottom of the front slot 34 in the shoe 31. In thusdisengaging the latch lever 35 from the pin-42 an appreciable liftingforce is transmitted through the spring 38 to the magazine proper, suchforce to a considerable extent counterbalancing the weight of themagazine and its contents. Having a convenient grip upon the lever. 52,the pressman swings themagazine open and at the same time readilycontinues to exert a lifting force on said lever with the result thatthe magazine and its swinging mounting are not subjected to unduestrains. The magazine is closed in the same manner and with the sameeffect as in the opening thereof. After the shoe 31 has swung into placeon the latch block a in final stage of the closing throw of themagazine, the'pressman releases latch lever 35 which is then acted uponby the spring 38, said lever thereupon re-engaging the pin 42, thetapered sides of the magazine with respect to the press in the latchedposition of the magazine. To accord with the vertical angularity of themagazine longitudinally thereof the latch block a is raised or-loweredon the anchoringstuds 49 and to accord with the angularity of saidmagazine laterally thereof, one end of the block' is set at a differentelevation than the other. In any event the latch block a. is

stationed so that the bottom of the shoe 31 will skirt the upper surfaceof said block when the magazine is swung into its closed position. Withthis relation obtaining between the block a and shoe 31, any forward orbackward adjustment of the block will leave. the latch lever 35 and.latch pin 42 in proper cooperative relation.

After the magazine is-fully closed and the latch lever 35 released, inlatching position, the spring 38, acting through said lever 35 and thepin 42, firmly holds the shoe. 31 inplace upon the block a. If thepressman should close the magazine merely by pushing itand Withoutlending any' support to the magazine through the handle of,

latchlever 35, the cam surface,40 at the tip of said lever will engagebeneath thexpin 42 and automatically tilt the lever 35 so that the notch41 therein'will catch said pin.

Included in the magazine structure is awind:

ing shaft 54 having drums 55thereon. Tapes'56 fastened to the back rest19 are wound upon said drums 55 when the shaft 54 is turne'd Arockerdisk 56 having a ratcheting connection, (not shown) with the shaft54 turns said-shaft stepby-step to advance the backrestl9. The mechanismfor rocking the disk 56, as in the disclosure in our said Patent No.1,694,015, includes an up right reciprocating rod 5'7 (Fig.4) This rod57 has a novel swiveling connection with the rocker disk 56 whichcompensates for the swinging movements of the magazine, thus avoidingany necessity of disconnecting said mechanism before the magazine isswung out of its operative position and again connecting the mechanismafter the magazine is returned to its operative position.

Saidswiveling connection is constructed with the post 20 as anelementthereof, the details of said connection being best seen in Fig.4. A

collar 58 on the post'20, is connected with the j reciprocating rod 57and is moved up and down on said post by the rod, rotational movementfofsaid collar being prevented by said rod. This collar 58 has a reducedsleeve-like portion 59, an annular shoulder or rest 60 being provided onsaid collar. A second collar 61, journaled on said reduced portion 59 ofsaid first collar, isconfined onthe first collar between the shoulder 60and a retaining ring 62, said ring being secured on said reduced collarportion 59 by means of set screws 63. A link 64 connects said secondcollar 61 with the rocker-disk 56 and serves to rock said 7 disk 56 whenthe said collar assembly is raised and lowered on the post 20 by theaction'of the rod 57.

Upon swinging the magazine, the link 64 causes I the collar 61 to turnupon the collar 58, this be-' ing the only eifectof such movement of themega:

rocker-disk 56.

thereof is concerned, remains unaifected in any position that may beoccupied by the 'swingable magazine. 1 V
